Neco 2018 Biology Question 38
Practice objective / multiple choice question 38 from the 2018 Neco Biology examination.
Ten random 1 m\(^2\) quadrats in a freshwater lake gave the following phytoplankton biomass (mg C m\(^{-2}\)): 120, 135, 110, 125, 130, 115, 140, 118, 132, 127. Estimate the mean phytoplankton biomass per m\(^2\) and its standard error. Assuming the average zooplankton biomass is 15\% of the phytoplankton biomass and the small‑fish biomass is 10\% of the zooplankton biomass, calculate the overall ecological efficiency from primary producers to small fish (percentage). Give the efficiency to the nearest whole percent.
